Refactor decoding of BIT STRINGs
Refactor decoding of BIT STRINGs so that the run-time code does not spend testing conditions that are known already at compile-time (which wastes time and produces unnecessary Dialyzer warnings). There are three ways to decode BIT STRINGs: 1) To a list of bit names (and {bit,Position} for unnamed positions) if the BIT STRING type has any bit names. 2a) To a list of ones and zeros if there are no named bits, and the compact_bit_string option was NOT given. 2b) To a {Unused,Bin} tuple if there are no named bits compact_bit_string option WAS given. Structure the decoding functions in the same way.
